Specification of Letters Patent.

Patented Aug-1, 1922.

Application filed February 15, 1921. Serial No. 445,215.

To all whom it may concern:

Be it known that zen of the United States, and a resident of t sion Devices and Guides for Thread; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in combined tension devices and guides for thread, such as yarn.

One object of the invention is to provide a simple and eilicient structure for applying tension to and for guiding yarn for spooling warp yarn spun with filling wind bobbins, but which may also be employed for spooling warp wind yarn, by placing the warp bobbins on Spindles.

A further object is to provide a tension device and guide which shall be automatic in operation and which shall require no adjustment to adapt the same for use with yarn of different grades or slzes.

A. further object is to so construct the device that the bars which apply the tension will not permit lumps and slugs to pass and which cannot be opened by the attendant to allow such lumps and slugs to pass.

A further object is to construct the device in such manner that the yarn will be cleaned of much of the leaf and trash which might pass through the guides as heretofore constructed.

lVith these and other objects in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my improvements; Figure 2 is a plan view, and Figure 3 1s a sec tional view.

1 represents the horizontal rod of a spooler on which a plurality of devices, each embodying my improvements, will be secured.

The said device comprises two jaws 2-3 to engage the rod 1 and when clamped to the latter by means of a bolt 1, constitutes bracket. The jaw 2 of this bracket is made with a lateral arm 5 which is recessed as at 6 and in line with this recessed portion of I, T'TAL Rrvmnn, a citithe bracket, an arm 7 is provided and so disposed'as to be parallel with but spaced from the rod 1,-said' arm or bar 7 having its free end somewhat rounded as at 8 and its upper face made flat. The arm or bar 7 constitutes the lower member of tension means, the upper member 9 of which is made with a flattened under face and a beveled end portion 10. The upper tension member 9 may be provided with an integral enlargement 11 to give sufficient weight thereto to insure the efficient performance of the fimction for which said member is intended. The upper tension member 9 18 provided with a shank 12 which is freely disposed between two ears 13-13 integral with the recessed jaw of the supporting bracket and a pin passes through said ears to form a stop 14; which will limit upward movement of said member 9. The shank 12 is recessed in opposite faces to receive the ears 13-13 and thus endwise displacement of the tension member 9 will be prevented. The jaw 3 of the supporting bracket is made with a socket or groove 15 to receive the shank 16 of a thread guide 17,-said socket or groove which received the shank 16 being so located that said shank will be clamped between the jaw 3 and the rod 1 and the thread guide located in front of the rod 1. It is evident however that the thread guide may be secured in place below the rod 1 without detracting from the efficiency thereof. The thread guide and its shank may be made of stout wire and the thread guide per se, is formed by bending the wire to spiral shape in such manner that a contracted space 18 will be provided between inner and outer convolutions for the passage and guidance of the yarn. By so form ing the thread or yarn guide, the yarn is guided smoothly over the rod 1 to the tension bars. Said wire guide is used only when bobbins are suspended beneath rod 1. if bobbins are placed on any device in front of rod 1 with ends pointing away from rod 1 and with yarn passing over another rod before it goes over rod 1 the wire guide is not required. The wire guide is merely to steady the yarn in its passage over rod 1 and cause it to pass without lateral vibration between the tension bars.

The yarn coming from the source of supply and after passing through the guide 17 as above explained, or over any other rod or wire in front of rod 1 will pass over the rod 1 and then between the members 7-9 of the tension means and finally to the spool. It will be observed that the upper tension memher 9 is freely movable; that its Weight will provide efficient tension on the yarn and that as the opposing faces of the two tension members are flat, the passage of leaf and trash with the yarn will be prevented and the resultant spooled yarn will be clean. The square edges of thetension bars 7 and 9 prevent the passage of lumps and slugs.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is Y 1, In a device of the character described, the combination with a bracket,'a lower fixed tension member on said bracket, and parallel ears projecting upwardlyfrom said bracket, of an upper tension member constituting a weight adapted normally to rest upon the lower tension member, said upper tension member having a part movable vertically between said parallel ears on the bracket, and a stop between said ears and over the part of the upper tension member passing between said ears.

2. In a device of the character described, the combination with a bracket and means for supporting the same, of an arm or bar projecting from said bracket and constituting a lower tension member, ears projecting upwardlyfrom said bracket and spaced apart, an upper tension member over and adapted normally to rest upon the lower tension member and freely movable relatively to the same, and a shank on said upper tensionmember passing between said ears J.
